I just found out on Fedora 20, that neither with Thunar nor Nautilus (I'm using Xfce4 here), I can't move file from /var/tmp to Trash. More precisely, in Nautilus the menu option is not available, while in Thunar it behaves as "Permanently delete". In either case, this is special-cased.

Why is that? Is Trash supposed to work only from home folder?

No Trash can typically handle anything. The problem is likely more that your userid does not have permissions to move these particular files and/or directories from /var/tmp.

To confirm drop to a shell and cd /var/tmp and check who the owner is of these files as well as the permissions on these files.

$ ls -la /var/tmp

Example

$ ls -la 
total 216

drwxr-xr-x. 24 root root  4096 Jan  7 02:20 ..

So if I were user saml when I ran Thunar or Nautilus and attempted touch any of the files owned by root I wouldn't be allowed to do so, in the above example.

But what user am I?

If you're in a shell and don't know what username you are (don't laugh, it happens) you can use the command:

$ who am i

  • This can't be the problem since the OP can actually delete (see the comment about thunar), it's just the trash that they can't use. I would guess it is because trash is implemented at the partition level and this is a tmpfs filesystem. – terdon Feb 6 '14 at 15:39
  • @terdon - thanks, you should be able to move files in/out of tmpfs. I'm pretty sure that I've done that with shmfs shares before. I would suspect then that it's an option in Thunar/Nautilus that's disallowing the movement of files "across" what they're perceiving as "non-local" disks. Analogous to local vs. network share. This is just a guess though. – slm Feb 6 '14 at 15:48
  • No, I meant that the way that nautilus/thunar implement trash (as opposed to delete) is by having a partition- or filesystem-wide .Trash folder and this might not work on tmpfs. I just found out that Trash is in ~/.local/share/Trash though so I'm probably wrong. Still think it has something to do with the different filesystem though :) – terdon Feb 6 '14 at 15:54
  • I can create, move them out or delete files at that location so that's not the problem. It's probably partitions: /var/tmp is not on tmpfs but on a regular ext4 (/tmp is on tmpfs). – Alois Mahdal Feb 6 '14 at 21:15
